40 S&W

The 40 S&W (aka ".40 cal") was developed after the FBI deemed the 10mm’s recoil to be a little too snappy for some of its … let’s say “more delicate” agents. 40 Smith & Wesson is especially popular for self-defense. See our top defensive ammo picks for 40 S&W here). 40 SW Bullet weights ranging from 105 to 200 grains are available, although many agree that 165 or 180 grains is optimal for personal protection. We work to keep bulk and defensive options ready for sale. You'll see our in-stock options below.

Here it is 2025 still buying my underwood 40 S/W 180 grain and loving my AMMO TO GO as always!

Hard hitting round that stopped a 110 pound mad pit-bull in its tracks with to body shots. This round is on the level nearly as much as my 45acp.
FRANK WOOD on 20rds – 40 S&W Winchester Defender 165gr. PDX1 Bonded JHP Ammo

In my opinion, the Winchester Ranger T series is the best EDC ammo out there in .40 S&W. It's extremely hard to find as well. I had been searching for it for quite some time and the only place I found it was at Ammo To Go.
